Tomi Valkeinen 66ae158543 ARM: dts: am437x-gp/epos-evm: fix panel compatible
[ Upstream commit c6b16761c6 ]

The LCD panel on AM4 GP EVMs and ePOS boards seems to be
osd070t1718-19ts. The current dts files say osd057T0559-34ts. Possibly
the panel has changed since the early EVMs, or there has been a mistake
with the panel type.

Update the DT files accordingly.

Sudeep Holla a4aaf1242c ARM: dts: am437x: replace linux,wakeup with wakeup-source property
Most of the legacy "linux,wakeup" boolean property is already replaced
with "wakeup-source". However few occurrences of old property has popped
up again, probably from the remnants in downstream trees.

Replace the legacy properties with the unified "wakeup-source" property
introduced in the commit aeda5003d0 ("Input: matrix_keypad - change
name of wakeup property to "wakeup-source"")

Dave Gerlach 865852a6e5 ARM: dts: am437x-gp-evm: Add state for ddr3 vtt toggle pin
Add pinctrl data for ddr_vtt_toggle pin so that it is configured
for proper state during DeepSleep0. The pin should enter DS0 off mode
and hold the line low so VTT regulator is kept off while suspended.
It is also important for the PULLUP to be set on this pin so that
on removal of isolation, the VTT line is pulled high as a requirement
for bringing the DDR3 out of self-refresh.

This toggling is dependent on the IO isolation controlled by the
wkup_m3. Without placing the IOs into isolation the DS0 states set for
the pin will not be latched into effect during suspend.

Tony Lindgren 572cf7d7b0 ARM: dts: Improve omap l4per idling with wlcore edge sensitive interrupt
The wl1835mod.pdf data sheet says this pretty clearly for WL_IRQ line:

"WLAN SDIO out-of-band interrupt line. Set to rising edge (active high)
by default."

And it seems this interrupt can be optionally configured to use falling
edge too since commit bd763482c8 ("wl18xx: wlan_irq: support platform
dependent interrupt types").

On omap4, if the wlcore interrupt is configured as level instead of edge,
L4PER will stop doing hardware based idling after ifconfig wlan0 down is
done and the WL_EN line is pulled down.

The symptoms show up with L4PER status registers no longer showing the
IDLEST bits as 2 but as 0 for all the active GPIO banks and for
L4PER_CLKCTRL. Also the l4per_pwrdm RET count stops increasing in
the /sys/kernel/debug/pm_debug/count.

While there is also probably a GPIO related issue that needs to be
still fixed, this change gets us to the point where we can have L4PER
idling.

I'm guessing wlcore was at some point configured to use level interrupts
because of edge handling issues in gpio-omap. However, with the recent
fixes to gpio-omap the edge interrupts seem to be working just fine.

Let's change it for all omap boards with wlcore interrupt set as level.

Franklin S Cooper Jr 78b02c36e4 ARM: dts: am437xx: Enable NAND dma prefetch by default
Currently the default method of prefetch polled shows the highest
possible read and write speed when minimal non NAND background
activity is being done. But it is also very CPU intensive to reach
these high speeds (CPU load of 99% via mtd performance tests). While
DMA prefetch only uses 50% of the CPU to achieve around 23% less in
top read and write performance.

However, as the non NAND CPU load increases the read and write
performance takes a large hit when using polled prefetch. Therefore,
prefetch dma mode ends up outperforming prefetch polled in general
"system level" test. So switch to using dma prefetch by default since
it is likely what most users would prefer.

state via pinctrl and IO daisy chain using generic wakeirq framework.
With commit 3fffd12839 ("i2c: allow specifying separate wakeup
interrupt in device tree") i2c core allows optional wakeirq to be
specified via device tree. Add wakeup irq entry to enable pixcir_i2c_ts
to wake the system from low power state.

Mugunthan V N 0731cbdd5f ARM: dts: am43xx: fix cd-gpios definition as per hardware design and dt binding docs
As per mmc device tree binding documentation card detect gpio has
to be active low signal. When a hardware is designed with active
high card detect, gpio polarity has to be changed with
cd-inverted dt property.

In AM43xx the card detect gpio is designed as active low gpio.
So correcting the dt card detect gpio definition.

Dave Gerlach 1e9f747400 ARM: dts: am437x-gp-evm: Add regulator-always-on and regulator-boot-on for RTC DCDCs
DCDC5 and DCDC6 supply rtc and need to be on for accessing the module.

On A1 revision of the TPS65218, FSEAL bit would be undefined without
coin-cell present which in many cases led to it being set, causing DCDC5
and DCDC6 to stay active, but also leading to unexplained failures when
it was not. On B1 revision, FSEAL is always 0 when no coin-cell is present
so this patch is required on boards with B1 revision to ever work. This
implementation works on boards with either A1 or B1 revision and makes
sure that DCDC5 and DCDC6 always stay active.

Marc Zyngier 7136d457f3 ARM: omap: convert wakeupgen to stacked domains
OMAP4/5 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.

This patch does just this, updating the DT files to actually
reflect what the HW provides.

BIG FAT WARNING: because the DTs were so far lying by not
exposing the WUGEN HW block, kernels with this patch applied
won't have any suspend-resume facility when booted with old DTs,
and old kernels with updated DTs won't even boot.

On a platform with this patch applied, the system looks like
